My first review--been here 3 years. I have tried just about EVERY component in the this section and the Captcha section. There were ALWAYS conflicts with other extensions on my site. This is the only one that worked, and the only one that works with RT templates. It's not universal: meaning, won't work for every form you might have. But if you need an easy to use and easy to modify spam/bot/spider filter on your "contact" form....this one rocks. I appreciate the developer's hard work. Support him and his paid extensions! (Joomla Extension mods-- I have zero relations with the guy). Good job!
